I just finished reading the book Nasdaq Trader's Toolkit by Rogan Labier. The way i understood it, Selectnet orders preferenced to an ECN where the order is hidden and not displayed on Level 2 will not execute against it. Can anyone shed some light on this. Thanks.
Thanks Turok for clearing that up but say Island or any other ECN has a hidden order to sell at 50 and let's say no Island orders come in to buy at 50 or higher, will the price on Level 2 bid higher than 50 leaving this hidden Island order to sell at 50 unexecuted?
